Operation
When compressed by the compressor (1.01), the air flows to the air cleaner (6.05), which contains a pressure regulating valve integrated.
After cleaning and then adjusting the pneumatic pressure of compressed air, the pressure regulating valve integrated to the air cleaner (6.05) sends the air to the compressed air tank (5.01) as well as to the four-circuit valve (4.03).
The compressed air tank (5.01) stores the air and uses it to clean the valve filter (6.05).
The four-circuit protective valve (4.03) supplies compressed air to the various pneumatic circuits of the brake system (service brake, parking brake, auxiliary circuits etc). As well as ensuring minimum pressure in each one of the circuits.
